BURNEB-REGULATING DEVICE;

Application filed November 2, 1925.

ting of its up and down movements.

The object of the invention generally stated is to provide an improved adjusting or regulating means whereby the oil receptacle which is mounted for up and down 16 movements may be readily and conveniently operated to vary the position of the receptacle, and which is adapted to sustain the receptacle in its adjusted position against accidental movement.

Briefly stated, I accomplish this result by means of an operating screw having a screwthreaded connection with a stationary-part on the stove or heater structure and having an operating handle located forwardly in said structure and having an operative connection between the rear end of the screw and the receptacle to be raised and lowered.

In the accompanying drawings, I have illustrated one en'lbodiment only of the in D vention, it being contemplated that various changes may be made by those skilled in the art without departing from the spiritand scope of the invention as expressed in the appended claims.

Figure 1 of the drawings is a fragmentary front elevational view of an oil stove having my improved ad ustlng means applied to a burner to raise and lower the same.

Fig. 2 1s a vertical sectional v1ew taken approximately in the plane of line 22 of fiig. 3 is a similar view taken approximately in the plane of line 33 of Fig. 1.

Fig. 4: is a rear view of the parts shown (I in Fig. 1.

In the embodiment selected for illustration, 7 designates an annular burner bowl of any ordinary or preferred construction communicating by means of a telescoping l! pipe connection 8 with a horizontally disposed oil supply pipe 9 leading to a convenient source of oil supply (not shown). 10 designates a horizontally disposed front plate extending lengthwise along the front ll of the stove and rigidly secured to the stove Serial No. 66,136.

structure in any suitable way (not shown). The front plate 10 comprises a vertical portion 11 and an upperrearwardly extending horizontal portion 12, the front or vertical portion being spaced a substantial distance forwardly of the horizontal supply pipe 9.

Rigidly secured to the front plate 10 and extending rearwardly therefrom beneath and beyond the upper portion 12 of this plate is a supporting bracket 13 in the form of a plate of substantial width having u per and lower flanges 1-1 and 15 and a f I 'ont flange 16. The upper flange 1a and the front flange .16 are respectively secured to the horizontal and vertical portions 11 and 12 of the front plate 10. Near their rear ends said upper and lower flanges 14 and 15 are extended laterally somewhat to provide ears 17 and 18 which are apertured to receive the lower section 19 of the telescoping pipe connection 8. At its lower end said pipe section 19 may be secured to the supply pipe 9 in any suitable way, being herein shown as welded thereto. At its upper end, the pipe section 19 is screw-threaded as indicated at 20 and a pair of nuts 21 located on opposite sides of theear 17serve to secure the bracket 13 rigidly to the pipe section.

The upper section of the telescoping pipe connection comprises a relatively smaller pipe section 22 depending from the burner bowl 7 at one edge thereof and communicating with the interior of the bowl. This pipe section 22 depends into the lower pipe section 19 for sliding engagement therewith, a suitable stuffing box 23 being provided to seal the joint.

The burner is adapted to be raised and lowered by the manipulation of a handle 2 1 mounted on the forward end of a horizontally disposed operating rod 25 which extends in a front to rear direction through the vertical portion 11 of the front plate 10, a suitable aperture being provided in the front plate to receive the rod 25. The operating handle as thus arranged is conveniently located so as to be readily accessible. At its rear end the rod 25 has a screw 27 rigid therewith and engaging a nut 28 rigid with the bracket 13. Hence, in the rotation of the rod by the handle 2d an axial movement is imparted to the rod which is trans mitted to the burner through means which will presently be described, to raise and lower the same. The nut 28 is in the term of a plate or block of "suitabie thickness which'is secured in thepresent instance to the bracket bymeans, of bolts .29. entered through lugs 30' struck up from the face of the bracket in perpendicular relation thereto, these lugs being suitably apertured to receive the bolts. v

The operative connectionbetween the screw and the burner comprises in the present instance a bellcrank lever 31 fulcrumed onfthebracket'13'as by means of abolt' 32, a washer33 being preferably interposed between the lever and the bracket to s )ace the lever. outwardly from the bracket. ne arm 34 of the lever' 31 has a pin-and-sl'ot connection 35 with a block 36 swivelled on the rear end of the rod 25,a portion of the rod extending rearwardly fromthe screw 27. litheotheror upper arm 37 l'rasa pin-and-slot connection 38 at its free end with thelower end ofmrann 39 rigidly secured at its upper end to "one edgeiof theburnerbowl adjacent the pipe section 22. The connection 28 may consist of a bolt 40 operating in a slot 41 in the lever arm 37 and also operating in a vertical guide slot 42 in the bracket 13.

a It will be seen that the axial movements imparted to the rod by turning the handle 24 will siving the lever31 to cause the burner bowl 7 to raise or lower, and that when the burner has beenadj'usted in any desired po sition it will be effectually sustained or lockeddnsuch position bya part of the operatingiueans itself, viz, the screw and nut the hitter it being observed, being rigid with the stove structure. Preferably the propoi'tioning' of the parts is such that the screw has a relatively snugly fitting engageinent-with the nut 28so that a positive rotational movementmust be imparted to the handle before the position of the burner can be altered. To thus lock the burner in its adjusted position is important, for the ellicient operation of the stove requires that the burner shall not be capable of accidental position upon tl'ieupper flangeof the bracket by means of one of the screws which connect the front plate to the bracket. i .I claim as my invention:

1. A; wicklcss oil burner comprising, in

combination, a stovebody, a hurncrbowl,

a vertical fuel sup 'ilypipe, a pipe connected to and carried by the bowl telescoping with the vertical supply pipe, a vertically movable support for the bowl, :1 pivoted lever having a pin and slot connection with said support and a shaft having rotatable screwthrcadcd engagement with a fixed portion of said stove body and having operative connection, with said pivoted lever.

2. wickless oil burner comprising, in

con'ibination, a burner bowl, means communicating with said bowl for thesupply of oil thereto, a vertically movable support for said howl, guiding means for the vertical rnoi'enient of said support and bowl, a rotatable shaft having screw-threaded engagelnent in a stationary bearing, and a stationarily pivoted bell crank, one arm thereof having an operative connection with said,

shaft and the other arm having operative connection with said support whereby the axial movement of said shaft cilects the vertical movement of said support.

In testimony whereof, I affixed my signature.

CHARLES M. FITCH.
